Specification of Letters Patent.

Application filed October 23, 1917. Serial No. 198,012.

To all whom it may concern:

Be it known that I, ALBERT H. SHERWOOD, a citizen of the United States, residing at Oroville, in the county of Butte and State of California, have invented new and useful Improvements in Adjustable Copy- Holders, of which the following is a specification.

This invention relates to an adjustable copy holder for typewriters.

One of the objects of the present invention is to provide a simple form of copy holder for typewriters which may be readily applied to or removed from the carriage of the typewriter, and which is so constructed that the sheet to be copied may be quickly inserted and adjusted with relation to a reading slot formed in the holder. Another object of the invention is to provide means for automatically feeding or advancing the holder in unison with the movement of the platen so that line after line will move into register with the reading slot as the work progresses. Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which- Figure 1 is a front view of the upper part of a typewriter, showing the application of the invention.

Fig. 2 is a side elevation of same.

Fig. 3 is a central, longitudinal section through the copy holder.

Fig. 4 is a cross section of same.

Fig. 5 is a side elevation of the spreader. Referring to the drawings in detail, A in dicates the upper portion of the main frame tracks upon which the carriage is supported, 4 the platen, 5 the spacing lever, 6 the pawl on the inner end of the spacing lever, and 7 the toothed ratchet or spacing wheel secured on the end of the platen. Suitably secured at each end of the carriage is a socket member 8, and adapted towbe-received by each socket member is :abracket arm 9, one being for a holder, generally indicated atlO.

This holder 10 is constructed of tin, aluminum, or other suitable sheet-like material. It is approximately semicircular in cross section and the front portion is prorovided for each socket. These socket mem ers 8 serve as supports vided with a reading slot 11. Adapted to be supported on the holder 10 is a cylinder 12, which is constructed of glass, celluloid or any other transparent or semi-transparent material. Secured on each end of the cylinder 12 is a bearing ring 13, and formed on the outer end of one of said rings is a plurality of ratchet teeth 14. Pivotally mounted, as at 15, on one of the brackets 9 is a pawl 16, and adapted to hold one end of said pawl in engagement with the spacing pawl 6 is a spring 17. The lower end of the pawl 16 passes directly under the spacing pawl 6, while the upper end 18 assumes a position which permits it to engage with the teeth 14 formed on the bearing ring 13 of the copy holder 10.

The cylinder 12 is provided for the purpose of receiving the sheet to be copied. This sheet is merely inserted in the cylinder from either end and when so inserted is held against the inner face of the cylinder by means of a spreader 19. This spreader consists of a ring 20 and two pairs of U- shaped cross spring arms 21, that is, insertion of the spreader in either end of the cylinder, after a sheet has been inserted, spreads the sheet or holds it in contact with the inner face of the cylinder, thus preventing it from collapsing and at the same time supporting it in a position where the typed or written matter contained thereon may be easily read through the reading slot 11.

The copy holder proper or the cylinder 12 may be lifted out of the holder or may be left in the holder when a sheet is to be inserted or removed. A pin 22, secured in the receiver 10, engages with the end bearing ring at the point shown in Fig. 3, thereby preventing the pawl member 18, when engaging the teeth, from moving the cylinder endwise or displacing it with relation to the reading slot 11. The cylinder is otherwise entirely free and independent as regards the receiver 10 and may, therefore, be quickly removed or replaced when desired. It is otherwise perfectly free to rotate in the receiver, and one of the features of the present invention is to provide means for automatically rotating the cylinder While the typing or copying of the sheet is taking place, so that line after line will automatically move into register with the reading slot while the work is proceeding.

. This is accomplished by transferring the movement of the platen, through the pawl 16, to the cylinder. For instance, if the spacing lever 5 is rocked-to rotate the platen one space, then it can readily be seen that the pawl 6 will engage the lower end of pawl 16 and also cause this to rock and bring the pawl into engagement with the teeth 14; and therebyrotate this one space. two. spaces a similar transfer will take place, while three spaces permit a triple spacing or movement of the copy holder or 3 cylinder 12.

v If it is desired to double space the copy which is being typed on the sheets placed,

on the platen and it happens that the data on the copy holder in the cylinder 12 is single spaced, then it is only necessary to depress the pawl 16 one space by inserting a pin 2% in a plate forming part of the bracket arm 9. This depression of the pawl 16 one space permits the pawl 6 to move one space without engaging the pawl 16, while ceiver 10 and a copy the remaining movement of the pawl 6 will engage the pawl 16 and move it one space. A double spacing of the sheet placed on the platen t can, therefore, take place while a single space only is transmitted to the copy holder. The pin 24 may be raised or lowered in openings formed in the plate so that it also becomes possible to triple space the platen and single space the copy holder or to triple space the platen and double space.

the copy holder. This is of considerable importance as it sometimes happens that the: sheet to becopied is single or double spaced,

while the sheet tov be. typed should be double ortriple spaced.

.While the pawll6 serves as a means for automatically turning the copy holder in unison with the platen and also permits a lost motion between the. platen and copy holder, I do not wish to limit myself to the:

specificmechanism shown assother makesof typewriters may require a considerable variation in construction. The'important feature involved is the provisionv of the reholder supported therein.

-.The sheet to be copied may be inserted within the cylinderwhere it is transparent or it maybe suitably attached to the outside of the cylinder, if desired, thereby permitting an opaque or semitransparent' material tobeused. The bearing rings 13 IJIOVlClGd serveas a means for'retaining the cylinder 12' out of contact with the surface of the receiver, thereby preventing the surface of the cylinder from becoming scratched or soiled through constant. rotation and use of same- The materials and finish of the several parts ofthedevice may besuch as the ex 5 pierience and judgment of the manufacturer may dictate.

- I wish itunderstood'. that various-changes If the spacing lever is operated for in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims and that I do not wish. to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Iietters Patent is- 1. A copy holder for typewriters compris ing a receiver secured: to and adapted to.

travel with the carriageof the typewriter, a
